STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH

This invention was made with government support under grant numbers GM113310 and CA008748 awarded by the National Institutes of Health. The government has certain rights in the invention.

BACKGROUND

Ubiquitin-like protein (UBL) modification pathways have emerged as important targets for drug discovery based on their vast roles in regulation, and on clinical and preclinical successes of proteasome inhibitors (e.g. bortezomib or carfelzomib), E3 inhibitors, and the NEDD8 E1 inhibitor (MLN4924) (e.g., see Ciechanover, A. Bioorg Med Chem 2013, 21:3400; and Bassermann, F.; Eichner, R.; Pagano, M. Biochim Biophys Acta 2014 1843(1):150-62). These chemical inhibitors of UBL pathways have also proven to be essential probes for dissecting multifactorial regulatory networks that were opaque to genetic approaches.

Currently, the FDA approved drugs that target the ubiquitin-proteasome system (UPS), bortezomib and carfilzomib, completely block proteasome activity (see Petroski, M. D.; and Deshaies, R. J. Nat. Rev. Mol. Cell Biol. 2005, 6:9; da Silva, S. R, et al. J. Med. Chem. 2013, 56:2165; Hideshima, T., et al. Cancer Res. 2001, 61:3071; Shi, D.; and Grossman, S. R. Cancer Biol. Ther. 2010, 10:737). Clinically, this leads to toxicity; 50% of the patient population taking either proteasome inhibitor exhibit grade 3 hematologic adverse events (thrombocytopenia and neutropenia) and nearly 15% suffer grade 4 adverse events (potentially life-threatening) (see Jagannath, S., et al. Clin Lymphoma Myeloma Leuk 2012, 12:310; Siegel, D. S., et al., Blood 2012, 120:2817; Curran, M. P.; and McKeage, K. Drugs 2009, 69:859). However, there are no currently available therapeutic agents that specifically target components of the UBL system such as the DCN1-UBC12 interaction.

The function of DCN1 is to bind the acetylated N-terminus of UBC12 (an E2 enzyme for the UBL NEDD8) and the “Cullin (or CUL)” family of proteins to act as a co-E3 promoting NEDD8 modification (neddylation) of the CULs (see Kurz, T., et al. Mol. Cell 2008, 29:23; Scott, D. C., et al. Mol. Cell 2010, 39:784; Kim, A. Y. et. al. J. Biol. Chem. 2008, 283:33211; and Scott, D. C., et al. Science 2011, 334:674). DCN1 is part of a dynamic signaling system that regulates ligation of both NEDD8 and ubiquitin (UB), which are among more than a dozen human UBLs that dynamically post-translationally modify and regulate the functions of thousands of different eukaryotic proteins. It is believed that inhibition of the DCN1-UBC12 interaction could regulate CRL activity without completely blocking neddylation and provide efficacious compounds with less severe off-target effects and toxicity relative to existing drugs that target the UPS system (see Sun, Y. Neoplasia 2006, 8:645; Petroski, M. D.; and Deshaies, R. J. Nat Rev Mol Cell Biol 2005, 6:9; Nakayama, K. I.; and Nakayama, K. Nat Rev Cancer 2006, 6:369).

Despite advances in small molecule regulation of UBL modification pathways, there is still a scarcity of compounds that are potent, efficacious, and selective inhibitors of Cullin neddylation and also effective in the treatment of abberant DCN1 expression associated with squamous cell carcinomas and other cancers and diseases in which the dysregulation of DCN1-dependent neddylation is involved. These needs and other needs are satisfied by the present invention.

Additional advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or can be learned by practice of the invention. The advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

DESCRIPTION

The present invention can be understood more readily by reference to the following detailed description of the invention and the Examples included therein.

A. Definitions

As used herein, nomenclature for compounds, including organic compounds, can be given using common names, IUPAC, IUBMB, or CAS recommendations for nomenclature. When one or more stereochemical features are present, Cahn-Ingold-Prelog rules for stereochemistry can be employed to designate stereochemical priority, E/Z specification, and the like. One of skill in the art can readily ascertain the structure of a compound if given a name, either by systemic reduction of the compound structure using naming conventions, or by commercially available software, such as CHEMDRAW™ (Cambridgesoft Corporation, U.S.A.).

As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a functional group,” “an alkyl,” or “a residue” includes mixtures of two or more such functional groups, alkyls, or residues, and the like.

Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, a further aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms a further aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10” is also disclosed. It is also understood that each unit between two particular units are also disclosed. For example, if 10 and 15 are disclosed, then 11, 12, 13, and 14 are also disclosed.

References in the specification and concluding claims to parts by weight of a particular element or component in a composition denotes the weight relationship between the element or component and any other elements or components in the composition or article for which a part by weight is expressed. Thus, in a compound containing 2 parts by weight of component X and 5 parts by weight component Y, X and Y are present at a weight ratio of 2:5, and are present in such ratio regardless of whether additional components are contained in the compound.

A weight percent (wt. %) of a component, unless specifically stated to the contrary, is based on the total weight of the formulation or composition in which the component is included.

As used herein, the terms “optional” or “optionally” means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

As used herein, the term “subject” can be a vertebrate, such as a mammal, a fish, a bird, a reptile, or an amphibian. Thus, the subject of the herein disclosed methods can be a human, non-human primate, horse, pig, rabbit, dog, sheep, goat, cow, cat, guinea pig or rodent. The term does not denote a particular age or sex. Thus, adult and newborn subjects, as well as fetuses, whether male or female, are intended to be covered. In one aspect, the subject is a mammal. A patient refers to a subject afflicted with a disease or disorder. The term “patient” includes human and veterinary subjects. In some aspects of the disclosed methods, the subject has been diagnosed with a need for treatment of one or more disorders, e.g., a neurodegenerative disease or disease of uncontrolled cellular proliferation, associated with DCN1-UBC12 interaction prior to the administering step. In some aspects of the disclosed method, the subject has been diagnosed with a need for inhibition of DCN1-mediated cullin-RING ligase activity activity prior to the administering step. In some aspects of the disclosed method, the subject has been diagnosed with a disorder of uncontrolled cellular proliferation, e.g., a cancer, prior to the administering step. In some aspects of the disclosed method, the subject has been diagnosed with a neurodegenerative disorder prior to the administering step. In some aspects of the disclosed method, the subject has been identified with a disorder treatable by inhibiting the DCN1-UBC12 interaction prior to the administering step. In some aspects of the disclosed method, the subject has been identified with a disorder treatable by inhibiting DCN1-mediated cullin-RING ligase activity prior to the administering step. In some aspects of the disclosed method, the subject has been identified with a bacterial or viral infection prior to the administering step. In some aspects of the disclosed method, the subject has been identified with a need for male contraception. In one aspect, a subject can be treated prophylactically with a compound or composition disclosed herein, as discussed herein elsewhere.

As used herein, the term “treatment” refers to the medical management of a patient with the intent to cure, ameliorate, stabilize, or prevent a disease, pathological condition, or disorder. This term includes active treatment, that is, treatment directed specifically toward the improvement of a disease, pathological condition, or disorder, and also includes causal treatment, that is, treatment directed toward removal of the cause of the associated disease, pathological condition, or disorder. In addition, this term includes palliative treatment, that is, treatment designed for the relief of symptoms rather than the curing of the disease, pathological condition, or disorder; preventative treatment, that is, treatment directed to minimizing or partially or completely inhibiting the development of the associated disease, pathological condition, or disorder; and supportive treatment, that is, treatment employed to supplement another specific therapy directed toward the improvement of the associated disease, pathological condition, or disorder. In various aspects, the term covers any treatment of a subject, including a mammal (e.g., a human), and includes: (i) preventing the disease from occurring in a subject that can be predisposed to the disease but has not yet been diagnosed as having it; (ii) inhibiting the disease, i.e., arresting its development; or (iii) relieving the disease, i.e., causing regression of the disease. In one aspect, the subject is a mammal such as a primate, and, in a further aspect, the subject is a human. The term “subject” also includes domesticated animals (e.g., cats, dogs, etc.), livestock (e.g., cattle, horses, pigs, sheep, goats, etc.), and laboratory animals (e.g., mouse, rabbit, rat, guinea pig, fruit fly, etc.).

As used herein, the term “prevent” or “preventing” refers to precluding, averting, obviating, forestalling, stopping, or hindering something from happening, especially by advance action. It is understood that where reduce, inhibit or prevent are used herein, unless specifically indicated otherwise, the use of the other two words is also expressly disclosed.

As used herein, the term “diagnosed” means having been subjected to a physical examination by a person of skill, for example, a physician, and found to have a condition that can be diagnosed or treated by the compounds, compositions, or methods disclosed herein. For example, “diagnosed with a disorder treatable by inhibiting the DCN1-UBC12 interaction” means having been subjected to a physical examination by a person of skill, for example, a physician, and found to have a condition that can be diagnosed or treated by a compound or composition that can inhibit the DCN1-UBC12 interaction. As a further example, “diagnosed with a need for inhibiting the DCN1-UBC12 interaction” refers to having been subjected to a physical examination by a person of skill, for example, a physician, and found to have a condition characterized by a DCN1-UBC12 interaction dysfunction. Such a diagnosis can be in reference to a disorder, such as a neurodegenerative disease, and the like, as discussed herein. For example, the term “diagnosed with a need for treatment of a disorder of uncontrolled cellular proliferation” refers to having been subjected to a physical examination by a person of skill, for example, a physician, and found to have a condition of uncontrolled cellular proliferation, e.g., a cancer, that can be treated by various therapeutic agents or methods, including, but not limited to, the disclosed compounds and/or products of the disclosed methods of making. For example, “diagnosed with a need for treatment of one or more disorders of uncontrolled cellular proliferation associated with a DCN1-UBC12 interaction dysfunction” means having been subjected to a physical examination by a person of skill, for example, a physician, and found to have one or more disorders of uncontrolled cellular proliferation, e.g., a cancer, associated with a DCN1-UBC12 interaction dysfunction.

As used herein, the phrase “identified to be in need of treatment for a disorder,” or the like, refers to selection of a subject based upon need for treatment of the disorder. For example, a subject can be identified as having a need for treatment of a disorder (e.g., a disorder related to a DCN1-UBC12 interaction dysfunction) based upon an earlier diagnosis by a person of skill and thereafter subjected to treatment for the disorder. It is contemplated that the identification can, in one aspect, be performed by a person different from the person making the diagnosis. It is also contemplated, in a further aspect, that the administration can be performed by one who subsequently performed the administration.

As used herein, the terms “administering” and “administration” refer to any method of providing a pharmaceutical preparation to a subject. Such methods are well known to those skilled in the art and include, but are not limited to, oral administration, transdermal administration, administration by inhalation, nasal administration, topical administration, intravaginal administration, ophthalmic administration, intraaural administration, intracerebral administration, rectal administration, sublingual administration, buccal administration, and parenteral administration, including injectable such as intravenous administration, intra-arterial administration, intramuscular administration, and subcutaneous administration. Administration can be continuous or intermittent. In various aspects, a preparation can be administered therapeutically; that is, administered to treat an existing disease or condition. In further various aspects, a preparation can be administered prophylactically; that is, administered for prevention of a disease or condition.

The term “contacting” as used herein refers to bringing a disclosed compound and a cell, a target protein(s) (e.g., the DCN1-UBC12 proteins), or other biological entity together in such a manner that the compound can affect the activity of the target, either directly; e.g., by interacting with the target protein(s) itself, or indirectly; i.e., by interacting with another molecule, co-factor, factor, or protein on which the activity of the target is dependent.

As used herein, the terms “effective amount” and “amount effective” refer to an amount that is sufficient to achieve the desired result or to have an effect on an undesired condition. For example, a “therapeutically effective amount” refers to an amount that is sufficient to achieve the desired therapeutic result or to have an effect on undesired symptoms, but is generally insufficient to cause adverse side effects. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration; the route of administration; the rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed and like factors well known in the medical arts. For example, it is well within the skill of the art to start doses of a compound at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. If desired, the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, single dose compositions can contain such amounts or submultiples thereof to make up the daily dose. The dosage can be adjusted by the individual physician in the event of any contraindications. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. Guidance can be found in the literature for appropriate dosages for given classes of pharmaceutical products. In further various aspects, a preparation can be administered in a “prophylactically effective amount”; that is, an amount effective for prevention of a disease or condition.

As used herein, “kit” means a collection of at least two components constituting the kit. Together, the components constitute a functional unit for a given purpose. Individual member components may be physically packaged together or separately. For example, a kit comprising an instruction for using the kit may or may not physically include the instruction with other individual member components. Instead, the instruction can be supplied as a separate member component, either in a paper form or an electronic form which may be supplied on computer readable memory device or downloaded from an internet website, or as recorded presentation.

As used herein, “instruction(s)” means documents describing relevant materials or methodologies pertaining to a kit. These materials may include any combination of the following: background information, list of components and their availability information (purchase information, etc.), brief or detailed protocols for using the kit, trouble-shooting, references, technical support, and any other related documents. Instructions can be supplied with the kit or as a separate member component, either as a paper form or an electronic form which may be supplied on computer readable memory device or downloaded from an internet website, or as recorded presentation. Instructions can comprise one or multiple documents, and are meant to include future updates.

As used herein, the terms “therapeutic agent” include any synthetic or naturally occurring biologically active compound or composition of matter which, when administered to an organism (human or nonhuman animal), induces a desired pharmacologic, immunogenic, and/or physiologic effect by local and/or systemic action. The term therefore encompasses those compounds or chemicals traditionally regarded as drugs, vaccines, and biopharmaceuticals including molecules such as proteins, peptides, hormones, nucleic acids, gene constructs and the like. Examples of therapeutic agents are described in well-known literature references such as the Merck Index (14^(th) edition), the Physicians' Desk Reference (64^(th) edition), and The Pharmacological Basis of Therapeutics (12^(th) edition), and they include, without limitation, medicaments; vitamins; mineral supplements; substances used for the treatment, prevention, diagnosis, cure or mitigation of a disease or illness; substances that affect the structure or function of the body, or pro-drugs, which become biologically active or more active after they have been placed in a physiological environment. For example, the term “therapeutic agent” includes compounds or compositions for use in all of the major therapeutic areas including, but not limited to, adjuvants; anti-infectives such as antibiotics and antiviral agents; analgesics and analgesic combinations, anorexics, anti-inflammatory agents, anti-epileptics, local and general anesthetics, hypnotics, sedatives, antipsychotic agents, neuroleptic agents, antidepressants, anxiolytics, antagonists, neuron blocking agents, anticholinergic and cholinomimetic agents, antimuscarinic and muscarinic agents, antiadrenergics, antiarrhythmics, antihypertensive agents, hormones, and nutrients, antiarthritics, antiasthmatic agents, anticonvulsants, antihistamines, antinauseants, antineoplastics, antipruritics, antipyretics; antispasmodics, cardiovascular preparations (including calcium channel blockers, beta-blockers, beta-agonists and antiarrythmics), antihypertensives, diuretics, vasodilators; central nervous system stimulants; cough and cold preparations; decongestants; diagnostics; hormones; bone growth stimulants and bone resorption inhibitors; immunosuppressives; muscle relaxants; psychostimulants; sedatives; tranquilizers; proteins, peptides, and fragments thereof (whether naturally occurring, chemically synthesized or recombinantly produced); and nucleic acid molecules (polymeric forms of two or more nucleotides, either ribonucleotides (RNA) or deoxyribonucleotides (DNA) including both double- and single-stranded molecules, gene constructs, expression vectors, antisense molecules and the like), small molecules (e.g., doxorubicin) and other biologically active macromolecules such as, for example, proteins and enzymes. The agent may be a biologically active agent used in medical, including veterinary, applications and in agriculture, such as with plants, as well as other areas. The term therapeutic agent also includes without limitation, medicaments; vitamins; mineral supplements; substances used for the treatment, prevention, diagnosis, cure or mitigation of disease or illness; or substances which affect the structure or function of the body; or pro-drugs, which become biologically active or more active after they have been placed in a predetermined physiological environment.

As used herein, “IC₅₀,” is intended to refer to the concentration of a substance (e.g., a compound or a drug) that is required for 50% inhibition of a biological process, or component of a process, including a protein, subunit, organelle, ribonucleoprotein, etc. For example, IC₅₀ refers to the half maximal (50%) inhibitory concentration (IC) of a substance as determined in a suitable assay. For example, an IC₅₀ for inhibiting DCN1-UBC12 interaction can be determined in an in vitro assay system.

The term “pharmaceutically acceptable” describes a material that is not biologically or otherwise undesirable, i.e., without causing an unacceptable level of undesirable biological effects or interacting in a deleterious manner.

As used herein, the term “derivative” refers to a compound having a structure derived from the structure of a parent compound (e.g., a compound disclosed herein) and whose structure is sufficiently similar to those disclosed herein and based upon that similarity, would be expected by one skilled in the art to exhibit the same or similar activities and utilities as the claimed compounds, or to induce, as a precursor, the same or similar activities and utilities as the claimed compounds. Exemplary derivatives include salts, esters, amides, salts of esters or amides, and N-oxides of a parent compound.

As used herein, the term “pharmaceutically acceptable carrier” refers to sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol and the like), carboxymethylcellulose and suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants. These compositions can also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms can be ensured by the inclusion of various antibacterial and antifungal agents such as paraben, chlorobutanol, phenol, sorbic acid and the like. It can also be desirable to include isotonic agents such as sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents, such as aluminum monostearate and gelatin, which delay absorption. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide, poly(orthoesters) and poly(anhydrides). Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues. The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable media just prior to use. Suitable inert carriers can include sugars such as lactose. Desirably, at least 95% by weight of the particles of the active ingredient have an effective particle size in the range of 0.01 to 10 micrometers.

A residue of a chemical species, as used in the specification and concluding claims, refers to the moiety that is the resulting product of the chemical species in a particular reaction scheme or subsequent formulation or chemical product, regardless of whether the moiety is actually obtained from the chemical species. Thus, an ethylene glycol residue in a polyester refers to one or more —OCH₂CH₂O— units in the polyester, regardless of whether ethylene glycol was used to prepare the polyester. Similarly, a sebacic acid residue in a polyester refers to one or more —CO(CH₂)₈CO— moieties in the polyester, regardless of whether the residue is obtained by reacting sebacic acid or an ester thereof to obtain the polyester.

As used herein, the term “substituted” is contemplated to include all permissible substituents of organic compounds. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, and aromatic and nonaromatic substituents of organic compounds. Illustrative substituents include, for example, those described below. The permissible substituents can be one or more and the same or different for appropriate organic compounds. For purposes of this disclosure, the heteroatoms, such as nitrogen, can have hydrogen substituents and/or any permissible substituents of organic compounds described herein which satisfy the valences of the heteroatoms. This disclosure is not intended to be limited in any manner by the permissible substituents of organic compounds. Also, the terms “substitution” or “substituted with” include the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound, e.g., a compound that does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, etc. It is also contemplated that, in certain aspects, unless expressly indicated to the contrary, individual substituents can be further optionally substituted (i.e., further substituted or unsubstituted).

In defining various terms, “A¹,” “A²,” “A³,” and “A⁴” are used herein as generic symbols to represent various specific substituents. These symbols can be any substituent, not limited to those disclosed herein, and when they are defined to be certain substituents in one instance, they can, in another instance, be defined as some other substituents.

The term “aliphatic” or “aliphatic group”, as used herein, denotes a hydrocarbon moiety that may be straight-chain (i.e., unbranched), branched, or cyclic (including fused, bridging, and spirofused polycyclic) and may be completely saturated or may contain one or more units of unsaturation, but which is not aromatic. Unless otherwise specified, aliphatic groups contain 1-20 carbon atoms. Aliphatic groups include, but are not limited to, linear or branched, alkyl, alkenyl, and alkynyl groups, and hybrids thereof such as (cycloalkyl)alkyl, (cycloalkenyl)alkyl or (cycloalkyl)alkenyl.

The term “alkyl” as used herein is a branched or unbranched saturated hydrocarbon group of 1 to 24 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, s-butyl, t-butyl, n-pentyl, isopentyl, s-pentyl, neopentyl, hexyl, heptyl, octyl, nonyl, decyl, dodecyl, tetradecyl, hexadecyl, eicosyl, tetracosyl, and the like. The alkyl group is acyclic. The alkyl group can be branched or unbranched. The alkyl group can also be substituted or unsubstituted. For example, the alkyl group can be substituted with one or more groups including, but not limited to, alkyl, cycloalkyl, alkoxy, amino, ether, halide, hydroxy, nitro, silyl, sulfo-oxo, or thiol, as described herein. A “lower alkyl” group is an alkyl group containing from one to six (e.g., from one to four) carbon atoms.

Throughout the specification “alkyl” is generally used to refer to both unsubstituted alkyl groups and substituted alkyl groups; however, substituted alkyl groups are also specifically referred to herein by identifying the specific substituent(s) on the alkyl group. For example, the term “halogenated alkyl” or “haloalkyl” specifically refers to an alkyl group that is substituted with one or more halide, e.g., fluorine, chlorine, bromine, or iodine. The term “alkoxyalkyl” specifically refers to an alkyl group that is substituted with one or more alkoxy groups, as described below. The term “alkylamino” specifically refers to an alkyl group that is substituted with one or more amino groups, as described below, and the like. When “alkyl” is used in one instance and a specific term such as “alkylalcohol” is used in another, it is not meant to imply that the term “alkyl” does not also refer to specific terms such as “alkylalcohol” and the like.

This practice is also used for other groups described herein. That is, while a term such as “cycloalkyl” refers to both unsubstituted and substituted cycloalkyl moieties, the substituted moieties can, in addition, be specifically identified herein; for example, a particular substituted cycloalkyl can be referred to as, e.g., an “alkylcycloalkyl.” Similarly, a substituted alkoxy can be specifically referred to as, e.g., a “halogenated alkoxy,” a particular substituted alkenyl can be, e.g., an “alkenylalcohol,” and the like. Again, the practice of using a general term, such as “cycloalkyl,” and a specific term, such as “alkylcycloalkyl,” is not meant to imply that the general term does not also include the specific term.

For example, with the phrase “an alkyl group comprising an amino group,” the amino group can be incorporated within the backbone of the alkyl group. Alternatively, the amino group can be attached to the backbone of the alkyl group. The nature of the group(s) that is (are) selected will determine if the first group is embedded or attached to the second group.

As described herein, compounds of the invention may contain “optionally substituted” moieties. In general, the term “substituted,” whether preceded by the term “optionally” or not, means that one or more hydrogens of the designated moiety are replaced with a suitable substituent. Unless otherwise indicated, an “optionally substituted” group may have a suitable substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position.

The term “leaving group” refers to an atom (or a group of atoms) with electron withdrawing ability that can be displaced as a stable species, taking with it the bonding electrons. Examples of suitable leaving groups include halides and sulfonate esters, including, but not limited to, triflate, mesylate, tosylate, brosylate, and halides.

The terms “hydrolysable group” and “hydrolysable moiety” refer to a functional group capable of undergoing hydrolysis, e.g., under basic or acidic conditions. Examples of hydrolysable residues include, without limitation, acid halides, activated carboxylic acids, and various protecting groups known in the art (see, for example, “Protective Groups in Organic Synthesis,” T. W. Greene, P. G. M. Wuts, Wiley-Interscience, 1999).

The term “organic residue” defines a carbon containing residue, i.e., a residue comprising at least one carbon atom, and includes but is not limited to the carbon-containing groups, residues, or radicals defined hereinabove. Organic residues can contain various heteroatoms, or be bonded to another molecule through a heteroatom, including oxygen, nitrogen, sulfur, phosphorus, or the like. Examples of organic residues include but are not limited alkyl or substituted alkyls, alkoxy or substituted alkoxy, mono or di-substituted amino, amide groups, etc. Organic residues can preferably comprise 1 to 18 carbon atoms, 1 to 15, carbon atoms, 1 to 12 carbon atoms, 1 to 8 carbon atoms, 1 to 6 carbon atoms, or 1 to 4 carbon atoms. In a further aspect, an organic residue can comprise 2 to 18 carbon atoms, 2 to 15, carbon atoms, 2 to 12 carbon atoms, 2 to 8 carbon atoms, 2 to 4 carbon atoms, or 2 to 4 carbon atoms.

A very close synonym of the term “residue” is the term “radical,” which as used in the specification and concluding claims, refers to a fragment, group, or substructure of a molecule described herein, regardless of how the molecule is prepared. For example, a 2,4-thiazolidinedione radical in a particular compound has the structure:

regardless of whether thiazolidinedione is used to prepare the compound. In some embodiments the radical (for example an alkyl) can be further modified (i.e., substituted alkyl) by having bonded thereto one or more “substituent radicals.” The number of atoms in a given radical is not critical to the present invention unless it is indicated to the contrary elsewhere herein.

“Organic radicals,” as the term is defined and used herein, contain one or more carbon atoms. An organic radical can have, for example, 1-26 carbon atoms, 1-18 carbon atoms, 1-12 carbon atoms, 1-8 carbon atoms, 1-6 carbon atoms, or 1-4 carbon atoms. In a further aspect, an organic radical can have 2-26 carbon atoms, 2-18 carbon atoms, 2-12 carbon atoms, 2-8 carbon atoms, 2-6 carbon atoms, or 2-4 carbon atoms. Organic radicals often have hydrogen bound to at least some of the carbon atoms of the organic radical. One example, of an organic radical that comprises no inorganic atoms is a 5, 6, 7, 8-tetrahydro-2-naphthyl radical. In some embodiments, an organic radical can contain 1-10 inorganic heteroatoms bound thereto or therein, including halogens, oxygen, sulfur, nitrogen, phosphorus, and the like. Examples of organic radicals include but are not limited to an alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, mono-substituted amino, di-substituted amino, acyloxy, cyano, carboxy, carboalkoxy, alkylcarboxamide, substituted alkylcarboxamide, dialkylcarboxamide, substituted dialkylcarboxamide, alkylsulfonyl, alkylsulfinyl, thioalkyl, thiohaloalkyl, alkoxy, substituted alkoxy, haloalkyl, haloalkoxy, aryl, substituted aryl, heteroaryl, heterocyclic, or substituted heterocyclic radicals, the terms are defined elsewhere herein. A few non-limiting examples of organic radicals that include heteroatoms include alkoxy radicals, trifluoromethoxy radicals, acetoxy radicals, dimethylamino radicals and the like.

“Inorganic radicals,” as the term is defined and used herein, contain no carbon atoms and therefore comprise only atoms other than carbon. Inorganic radicals comprise bonded combinations of atoms selected from hydrogen, nitrogen, oxygen, silicon, phosphorus, sulfur, selenium, and halogens such as fluorine, chlorine, bromine, and iodine, which can be present individually or bonded together in their chemically stable combinations. Inorganic radicals have 10 or fewer, or preferably one to six or one to four inorganic atoms as listed above bonded together. Examples of inorganic radicals include, but not limited to, amino, hydroxy, halogens, nitro, thiol, sulfate, phosphate, and like commonly known inorganic radicals. The inorganic radicals do not have bonded therein the metallic elements of the periodic table (such as the alkali metals, alkaline earth metals, transition metals, lanthanide metals, or actinide metals), although such metal ions can sometimes serve as a pharmaceutically acceptable cation for anionic inorganic radicals such as a sulfate, phosphate, or like anionic inorganic radical. Inorganic radicals do not comprise metalloids elements such as boron, aluminum, gallium, germanium, arsenic, tin, lead, or tellurium, or the noble gas elements, unless otherwise specifically indicated elsewhere herein.

Compounds described herein can contain one or more double bonds and, thus, potentially give rise to cis/trans (E/Z) isomers, as well as other conformational isomers. Unless stated to the contrary, the invention includes all such possible isomers, as well as mixtures of such isomers.

Unless stated to the contrary, a formula with chemical bonds shown only as solid lines and not as wedges or dashed lines contemplates each possible isomer, e.g., each enantiomer and diastereomer, and a mixture of isomers, such as a racemic or scalemic mixture. Compounds described herein can contain one or more asymmetric centers and, thus, potentially give rise to diastereomers and optical isomers. Unless stated to the contrary, the present invention includes all such possible diastereomers as well as their racemic mixtures, their substantially pure resolved enantiomers, all possible geometric isomers, and pharmaceutically acceptable salts thereof. Mixtures of stereoisomers, as well as isolated specific stereoisomers, are also included. During the course of the synthetic procedures used to prepare such compounds, or in using racemization or epimerization procedures known to those skilled in the art, the products of such procedures can be a mixture of stereoisomers.

Many organic compounds exist in optically active forms having the ability to rotate the plane of plane-polarized light. In describing an optically active compound, the prefixes D and L or R and S are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and l or (+) and (−) are employed to designate the sign of rotation of plane-polarized light by the compound, with (−) or meaning that the compound is levorotatory. A compound prefixed with (+) or d is dextrorotatory. For a given chemical structure, these compounds, called stereoisomers, are identical except that they are non-superimposable mirror images of one another. A specific stereoisomer can also be referred to as an enantiomer, and a mixture of such isomers is often called an enantiomeric mixture. A 50:50 mixture of enantiomers is referred to as a racemic mixture. Many of the compounds described herein can have one or more chiral centers and therefore can exist in different enantiomeric forms. If desired, a chiral carbon can be designated with an asterisk (*). When bonds to the chiral carbon are depicted as straight lines in the disclosed formulas, it is understood that both the (R) and (S) configurations of the chiral carbon, and hence both enantiomers and mixtures thereof, are embraced within the formula. As is used in the art, when it is desired to specify the absolute configuration about a chiral carbon, one of the bonds to the chiral carbon can be depicted as a wedge (bonds to atoms above the plane) and the other can be depicted as a series or wedge of short parallel lines is (bonds to atoms below the plane). The Cahn-Inglod-Prelog system can be used to assign the (R) or (S) configuration to a chiral carbon.

Compounds described herein comprise atoms in both their natural isotopic abundance and in non-natural abundance. The disclosed compounds can be isotopically-labeled or isotopically-substituted compounds identical to those described, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as ²H, ³H, ¹³C, ¹⁴C, ¹⁵N, ¹⁸O, ¹⁷O, ³⁵S, ¹⁸F, and ³⁶Cl, respectively. Compounds further comprise prodrugs thereof, and pharmaceutically acceptable salts of said compounds or of said prodrugs which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain isotopically-labeled compounds of the present invention, for example those into which radioactive isotopes such as ³H and ¹⁴C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e., ³H, and carbon-14, i.e., ¹⁴C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium, i.e., ²H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labeled compounds of the present invention and prodrugs thereof can generally be prepared by carrying out the procedures below, by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent.

The compounds described in the invention can be present as a solvate. In some cases, the solvent used to prepare the solvate is an aqueous solution, and the solvate is then often referred to as a hydrate. The compounds can be present as a hydrate, which can be obtained, for example, by crystallization from a solvent or from aqueous solution. In this connection, one, two, three or any arbitrary number of solvate or water molecules can combine with the compounds according to the invention to form solvates and hydrates. Unless stated to the contrary, the invention includes all such possible solvates.

The term “co-crystal” means a physical association of two or more molecules which are added together prior to crystallization. In certain instances, the two or more molecules may owe their stability through non-covalent interaction. One or more components of this molecular complex provide a stable framework in the crystalline lattice. In certain instances, the guest molecules are incorporated in the crystalline lattice as anhydrates or solvates, see e.g., “Crystal Engineering of the Composition of Pharmaceutical Phases. Do Pharmaceutical Co-crystals Represent a New Path to Improved Medicines?” Almarasson, O., et al., The Royal Society of Chemistry, 1889-1896, 2004. Examples of co-crystals include p-toluenesulfonic acid and benzenesulfonic acid.

It is also appreciated that certain compounds described herein can be present as an equilibrium of tautomers. For example, ketones with an α-hydrogen can exist in an equilibrium of the keto form and the enol form.

Likewise, amides with an N-hydrogen can exist in an equilibrium of the amide form and the imidic acid form. As another example, pyrazoles can exist in two tautomeric forms, N¹-unsubstituted, 3-R³ and N¹-unsubstituted, 5-R³ as shown below.

Unless stated to the contrary, the invention includes all such possible tautomers.

It is known that chemical substances form solids which are present in different states of order which are termed polymorphic forms or modifications. The different modifications of a polymorphic substance can differ greatly in their physical properties. The compounds according to the invention can be present in different polymorphic forms, with it being possible for particular modifications to be metastable. Unless stated to the contrary, the invention includes all such possible polymorphic forms.

In some aspects, a structure of a compound can be represented by a formula:

which is understood to be equivalent to a formula:

n is typically an integer. That is, R^(n) is understood to represent five independent substituents, R^(n(a)), R^(n(b)), R^(n(c)), R^(n(d)), and R^(n(e)). By “independent substituents,” it is meant that each R substituent can be independently defined. For example, if in one instance R^(n(a)) is halogen, then R^(n(b)) is not necessarily halogen in that instance.

Certain materials, compounds, compositions, and components disclosed herein can be obtained commercially or readily synthesized using techniques generally known to those of skill in the art. For example, the starting materials and reagents used in preparing the disclosed compounds and compositions are either available from commercial suppliers such as Aldrich Chemical Co., (Milwaukee, Wis.), Acros Organics (Morris Plains, N.J.), Fisher Scientific (Pittsburgh, Pa.), or Sigma (St. Louis, Mo.) or are prepared by methods known to those skilled in the art following procedures set forth in references such as Fieser and Fieser's Reagents for Organic Synthesis, Volumes 1-17 (John Wiley and Sons, 1991); Rodd's Chemistry of Carbon Compounds, Volumes 1-5 and Supplementals (Elsevier Science Publishers, 1989); Organic Reactions, Volumes 1-40 (John Wiley and Sons, 1991); March's Advanced Organic Chemistry, (John Wiley and Sons, 4th Edition); and Larock's Comprehensive Organic Transformations (VCH Publishers Inc., 1989).

Unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not actually recite an order to be followed by its steps or it is not otherwise specifically stated in the claims or descriptions that the steps are to be limited to a specific order, it is no way intended that an order be inferred, in any respect. This holds for any possible non-express basis for interpretation, including: matters of logic with respect to arrangement of steps or operational flow; plain meaning derived from grammatical organization or punctuation; and the number or type of embodiments described in the specification.

Disclosed are the components to be used to prepare the compositions of the invention as well as the compositions themselves to be used within the methods disclosed herein. These and other materials are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these materials are disclosed that while specific reference of each various individual and collective combinations and permutation of these compounds cannot be explicitly disclosed, each is specifically contemplated and described herein. For example, if a particular compound is disclosed and discussed and a number of modifications that can be made to a number of molecules including the compounds are discussed, specifically contemplated is each and every combination and permutation of the compound and the modifications that are possible unless specifically indicated to the contrary. Thus, if a class of molecules A, B, and C are disclosed as well as a class of molecules D, E, and F and an example of a combination molecule, A-D is disclosed, then even if each is not individually recited each is individually and collectively contemplated meaning combinations, A-E, A-F, B-D, B-E, B-F, C-D, C-E, and C-F are considered disclosed. Likewise, any subset or combination of these is also disclosed. Thus, for example, the sub-group of A-E, B-F, and C-E would be considered disclosed. This concept applies to all aspects of this application including, but not limited to, steps in methods of making and using the compositions of the invention. Thus, if there are a variety of additional steps that can be performed it is understood that each of these additional steps can be performed with any specific embodiment or combination of embodiments of the methods of the invention.

It is understood that the compositions disclosed herein have certain functions. Disclosed herein are certain structural requirements for performing the disclosed functions, and it is understood that there are a variety of structures that can perform the same function that are related to the disclosed structures, and that these structures will typically achieve the same result.

2. Determining a Therapeutically Effective Amount

Toxicity and therapeutic efficacy of the disclosed compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e. g., for determining the LD₅₀ (the dose lethal to 50% of the population) and the ED₅₀ (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD₅₀/ED₅₀. Compounds that exhibit large therapeutic indices can be desirable. While compounds that exhibit toxic side effects can be used, care should be taken to design a delivery system that targets such compounds to the site of affected tissue in order to minimize potential damage to uninfected cells and, thereby, reduce side effects.

Data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED₅₀ with little or no toxicity. Dosages can vary within this range depending upon the dosage form employed and the route of administration utilized. For any compound used in disclosed herein, the therapeutically effective dose can be estimated initially from cell culture assays. A dose can be formulated in animal models to achieve a circulating plasma concentration range that includes the IC₅₀ as determined in cell culture experiments. Such information can be used to more accurately determine useful doses in humans. Levels in plasma can be measured, for example, by high performance liquid chromatography.

Suitable daily doses for the treatment or prevention of a disorder described herein can be readily determined by those skilled in the art. A recommended dose of a compound of a compound disclosed herein can be from about 0.1 mg to about 1000 mg per day, e.g., from about 0.1 to about 500 mg/kg/day, 0.1 to about 250 mg/kg/day, or 0.1 to about 100 mg/kg/day, per kg of body weight, given as a single dose, a single once-a-day dose, or as divided doses throughout a selected time period.

The anti-cancer activity of the disclosed therapies can be determined by using various experimental animal models of such as the SCID mouse model or nude mice with human tumor grafts known in the art and described in Yamanaka, 2001, Microbiol Immunol 2001; 45 (7): 507-14.

The disclosed protocols and compositions can be tested in vitro, and then in vivo, for the desired therapeutic or prophylactic activity, prior to use in humans. For example, in vitro assays which can be used to determine whether administration of a specific therapeutic protocol is indicated, include in vitro cell culture assays in which a patient tissue sample is grown in culture, and exposed to or otherwise administered a protocol, and the effect of such protocol upon the tissue sample is observed.

A lower level of proliferation or survival of the contacted cells can indicate that the therapy can be effective to treat a selected disorder in a subject. Alternatively, instead of culturing cells from a patient, protocols can be screened using cells of a tumor or malignant cell line. Many assays known in the art can be used to assess such survival and/or growth; for example, cell proliferation can be assayed by measuring ³H-thymidine incorporation, by direct cell count, by detecting changes in transcriptional activity of known genes such as proto-oncogenes or cell cycle markers; cell viability can be assessed by trypan blue staining, while differentiation can be assessed visually based on changes in morphology, etc.

Compounds for use in therapy can be tested in suitable animal model systems prior to testing in humans, including but not limited to in rats, mice, chicken, cows, monkeys, rabbits, etc. The principle animal models for cancer known in the art and widely used include mice, such as described in Hann et al., 2001, Curr Opin Cell Biol 2001, 13 (6): 778-84, which is incorporated herein by reference in its entirety.

Further, any assays known to those skilled in the art can be used to evaluate the prophylactic and/or therapeutic utility of the combinatorial therapies disclosed herein for treatment, prophylaxis, management or amelioration of one or more symptoms associated with the disease or disorder as described hereinabove.

4. Prophylactic Treatment

In a further aspect, the disclosed compounds, compositions, and methods can be used prophylactically, i.e., to prevent progression to a neoplastic or malignant state, including but not limited to those disorders listed above. Such prophylactic use is indicated in conditions known or suspected of preceding progression to neoplasia or cancer, in particular, where non-neoplastic cell growth consisting of hyperplasia, metaplasia, or most particularly, dysplasia has occurred (for review of such abnormal growth conditions, see Robbins and Angell, 1976, Basic Pathology, 2d Ed., W.B. Saunders Co., Philadelphia, pp. 68-79.) Hyperplasia is a form of controlled cell proliferation involving an increase in cell number in a tissue or organ, without significant alteration in structure or function. As but one example, endometrial hyperplasia often precedes endometrial cancer. Metaplasia is a form of controlled cell growth in which one type of adult or fully differentiated cell substitutes for another type of adult cell. Metaplasia can occur in epithelial or connective tissue cells. A typical metaplasia involves a somewhat disorderly metaplastic epithelium. Dysplasia is frequently a forerunner of cancer, and is found mainly in the epithelia; it is the most disorderly form of non-neoplastic cell growth, involving a loss in individual cell uniformity and in the architectural orientation of cells. Dysplastic cells often have abnormally large, deeply stained nuclei, and exhibit pleomorphism. Dysplasia characteristically occurs where there exists chronic irritation or inflammation, and is often found in the cervix, respiratory passages, oral cavity, and gall bladder.

1. General Chemistry Methods

All moisture sensitive reactions were performed using syringe-septum techniques under an atmosphere of either dry N₂ or dry argon unless otherwise noted. All glassware was dried in an oven at 140° C. for a minimum of 6 hr or flame-dried under an atmosphere of dry nitrogen prior to use. Reactions carried out at −78° C. employed a CO₂(s)/acetone bath. Dry methylene chloride, tetrhydrofuran, diethylether, toluene, dimethylformamide, and acetonitrile were dried using an aluminum oxide column. All degassed solvents were prepared using the freeze/pump/thaw method (×3). Methanol, acetonitrile, and N,N-dimethylformamide were stored over molecular sieves (3 Å). Deuterated chloroform was stored over anhydrous potassium carbonate. Reactions were monitored by TLC analysis (pre-coated silica gel 60 F₂₅₄ plates, 250 μm layer thickness) and visualized by using UV lamp (254 nm) or by staining with either Vaughn's reagent (4.8 g of (NH₄)₆Mo₇O₂₄.4H₂O and 0.2 g of Ce(SO₄)₂ in 100 mL of a 3.5 N H₂SO₄) or a potassium permanganate solution (1.5 g of KMnO₄ and 1.5 g of K₂CO₃ in 100 mL of a 0.1% NaOH solution). Flash column chromatography was performed using a Biotage Isolera one and Biotage KP-SIL SNAP cartridges. Microwave reactions were performed on a Biotage Initiator microwave reactor. Unless otherwise indicated, all NMR data were collected at room temperature in CDCl₃ or (CD₃)₂SO on a 400 or 600 MHz Bruker instrument. Chemical shifts (6) are reported in parts per million (ppm) with internal CHCl₃ (δ 7.26 ppm for ¹H and 77.00 ppm for ¹³C), or internal trimethylsilane (TMS) (δ 0.00 ppm for ¹H and 0.0 ppm for ¹³C), as the reference. ¹H NMR data are reported as follows: chemical shift, multiplicity (s=singlet, bs=broad singlet, d=doublet, t=triplet, q=quartet, p=pentet, sext=sextet, sep=septet, m=multiplet, dd=doublet of doublets, dt=doublet of triplets, td=triplet of doublets, qd=quartet of doublets), coupling constant(s) (J) in Hertz (Hz), and integration. The purity of all final compounds was assessed using LC/MS/UV/ELSD using a Waters Acquity UPLC with the purity being assigned as the average determined by UV/Vis and ELSD.

3. Biology Methods

a. TR-FRET Assay

The TR-FRET assay is illustrated in FIG. 3A and FIG. 3B. The TR-FRET assay cocktail was prepared by mixing 50 nM Biotin-DCN1^(P), 20 nM AlexaFluor488 UBC12 peptide, and 2.5 nM Tb-Streptavidin conjugate (Life Technologies) in 25 mM Hepes, 10 mM NaCl, 0.1% Triton X-100, 0.5 mM DTT, pH 7.5. 20 ul of the cocktail was aliquoted out into black 384-well plates (Corning8849BC) using the WellMate and incubated for about 1 hour. Compounds were introduced to the desired concentration using the Biomek and the samples were incubated at r.t. for 60 min. The TR-FRET signal was read by the Pherastar plate-reader.

IC₅₀ data were calculated as previously described (Stewart et al, Cell Rep. 2014 Nov. 6; 9(3):829-41. doi: 10.1016/j.celrep.2014.09.028. Epub 2014 Oct. 23). Briefly, concentration-response data were analyzed using a custom script written in the R language (R Core Team (2013). R: A language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, Austria). Briefly, compounds were modeled by the four-parameter log-logistic function (“Hill equation”):

y=y ₀+(y _(Fin) −y ₀)/(1+(EC ₅₀ /x)^(−Hill))

where y is activity, x=log concentration, EC₅₀ is the log concentration at half-maximal observed response, and y₀ and y_(Fin) are the responses at zero and infinite concentrations, respectively.

The Hill parameters were estimated using the drm function in the R drc package (Ritz, C. & Streibig, J. C. (2005) Bioassay Analysis using R. J. Statist. Software, Vol 12, Issue 5) with modified arguments specifying parameter constraints and a custom-written function for estimating initial parameter values. To provide a robust estimate of model parameters, an outlier removal approach employing leave-one-out cross-validation was performed. Finally, the confidence intervals for model parameters were determined using a bootstrap approach. The best fit Hill parameters were used to define a base curve. The residuals from the model fit were sampled, with replacement, and added to the base curve at each observed concentration. The resulting dose-response curve was refit using the procedure described above to generate a new set of Hill parameters. This process was repeated 200 times to generate a distribution for each Hill parameter from which 95% confidence intervals could be obtained.

b. Pulse-Chase Assays

The Pulse-Chase assay and related data are illustrated in FIG. 4A-C. Compound inhibition of Dcn1^(P)-mediated co-E3 activity was monitored using pulse-chase assays to exclusively monitor effects of Nedd8 transfer to Cul2 without sensing earlier steps in the reaction. For the “pulse”, 10 μM. of Ubc12 was loaded for 15 minutes at room temperature with 0.2 μM. APPBP1/UBA3, 15 μM. [^(FAM)]-Nedd8, in 50 mM Hepes, 100 mM NaCl, 1.25 mM ATP, 2.5 mM MgCl₂, pH 7.5. Load reactions were quenched by the addition of EDTA to 50 mM and incubated on ice for 5 minutes. Chase reactions involved dilution of the UBC12˜[^(FAM)]-Nedd8 thioester conjugate to 40 nM in 50 mM Tris, 50 mM NaCl, 50 mM EDTA, 0.5 mg/mL BSA, pH 6.8. Chase reactions were initiated at 0° C. by the addition of pre-mixed CUL2^(CTD):DCN1^(P) complexes, with or without the indicated concentrations of small molecule inhibitor, at a final concentration of 125 nM. Aliquots were removed at the indicated times and quenched with 2×SDS-PAGE sample buffer. Reaction products were heated at 70° C. for 1.5 minutes and separated on 4-12% NuPAGE gels (Invitrogen). Fluorescent gels were visualized by scanning on a Typhoon imager (GE).

C. Cell Lysis and Western Blot

Cell pellets harvested from a 6 well dish were resuspended in 30-40 μL of lysis buffer (50 mM Tris, 150 mM NaCl, 0.5% NP-40, 0.1% SDS, 6.5 M. Urea, 2 mM 1,10-orthophenanthroline, 1× Halt Protease and Phosphatase inhibitor cocktail (ThermoFisher), 0.25 kU Universal Nuclease (ThermoFisher), pH 7.5). Cell pellet suspensions were incubated on ice for 25 minutes with occasional mixing by pipetting up and down. Lysates were cleared by centrifugation at 13 K rpm for 20 minutes and the supernatant was removed as total cell lysate sample. Protein concentration of the cell lysate was determined by BCA assay (Pierce) using BSA as a control. Cell lysates were diluted into 2×SDS-PAGE sample buffer such that 25 μg of total protein was loaded per well. Samples were heated at 95° C. for 2 minutes, briefly cleared by pulse centrifugation, and separated on 4-12% NuPAGE gels (Invitrogen). Gels were transferred to PVDF membranes (BIO-RAD) at 100V for 90 minutes at 4° C. Membranes were blocked for 1 hour in blocking buffer consisting of 1×TBS, 0.1% Tween-20, and 5% Blotting grade non-fat dry milk (BIO-RAD). Primary antibodies were prepared in blocking buffer and incubated with membranes overnight at 4° C. with rocking. Membranes were extensively washed in 1×TBS, 0.1% Tween-20. Secondary antibodies were prepared in blocking buffer according to the manufactures recommendations and incubated with membranes for 1 hour at room temperature. After extensive washing the membranes were developed with SuperSignal West Pico Chemiluminescent substrate (ThermoFisher) and developed by film exposure (HyBlot CL, Denville scientific).

4. Solubility

Solubility assays were carried out on a Biomek FX lab automation workstation (Beckman Coulter, Inc., Fullerton, Calif.) using μSOL Evolution software (pION Inc., Woburn, Mass.). The detailed method is described as following. Compound stock (10 mM in DMSO, 10 μL) was added to 1-propanol (190 μL) to make a reference stock plate. Reference stock solution (5 μL) was mixed with 1-propanol (70 μL) and citrate phosphate buffered saline (75 μL) to make the reference plate which was then measured with UV detection. Test compound stock (10 mM, 6 μL) was added to buffer (594 μL) in a 96-well storage plate and mixed. The storage plate was sealed and incubated at room temperature for 18 hours. The suspension was then filtered through a 96-well filter plate (pION Inc., Woburn, Mass.). Filtrate (75 μL) was mixed with 1 propanol (75 μL) to make the sample plate, and the UV spectrum (250 nm-500 nm) of the sample plate was read. Calculation was carried out by μSOL Evolution software based on the AUC (area under curve) of UV spectrum of the sample plate and the reference plate. All compounds were tested in triplicate.

5. Permeability

Parallel Artificial Membrane Permeability Assay (PAMPA) was conducted on a Biomek FX lab automation workstation (Beckman Coulter, Inc., Fullerton, Calif.) using PAMPA evolution 96 command software (pION Inc., Woburn, Mass.). Test compound stock (10 mM in DMSO, 3 μL) was mixed with citrate phosphate buffered saline (597 μL) to make diluted test compound. Diluted test compound (150 μL) was transferred to a UV plate (pION Inc., Woburn, Mass.) and the UV spectrum (250 nm-500 nm) was read as the reference plate. Each well of the donor plate in a PAMPA sandwich plate (pION Inc., Woburn, Mass.) contained a filter that was painted on one side with 4 μL GIT lipid (pION Inc., Woburn, Mass.) to form a membrane. Each well in the acceptor plate in a PAMPA sandwich, preloaded with magnetic stir bars, was filled with acceptor solution buffer (200 pION Inc., Woburn, Mass.). The donor plate was filled with diluted test compound (180 μL). The PAMPA sandwich was assembled by placing the donor plate over the acceptor plate. The combined PAMPA plate was placed on a pIon Gut-box™, a stirring apparatus that allows equilibrium to be reached quicker. Aqueous Boundary Layer of the pIon Gut-box™ was set to 40 μm and the compounds stirred for 30 minutes. The UV spectrum (250 nm-500 nm) of the donor and the acceptor were read. The permeability coefficient was calculated using PAMPA evolution 96 command software (pION Inc., Woburn, Mass.) based on the whole spectrum measured from the reference plate, the donor plate, and the acceptor plate. All compounds were tested in triplicates.

6. In Vivo Pharmacokinetic (PK) Methods

The first in vivo experiment was an IV dose ranging in adult female C57BL/6 mice that establishes acute tolerability and rough plasma PK parameters (using a single animal per dose/time point). Clinical signs and symptoms were monitored daily (weight loss, disruption of locomotor coordination, hunching, lack of grooming, lethargy, etc.) and organ function (kidney, liver, blood) and tissue histopathology (major organs) checked after 2 days. Dosage levels were estimated based on in vitro cytotoxicity and efficacy studies previously performed for the new chemical entity (NCE) and comparison to toxicity of structurally and/or pharmacologically similar compounds. Three dosages were selected (i.e., low, mid, and high) from a range of dosages (this generally ranges between 1 and 200 mg/kg). Six mice/dosage group were administered a single IV dosage of compound on day 1. Administration of compound began with the lowest dosage group, and were only escalated if there were no obvious immediate negative consequences (e.g., death, convulsion, ataxia, aberrant behavior, or evident pain observed within 15 minutes of observation). Dosage escalation was continued until serious adverse events were observed or the high dosage was reached (usually a maximum of 200 mg/kg). Once dosing was complete, animals were observed for 2 days. During this period, a single retro-orbital blood sample (100 μL) was collected from each mouse in the study (at 5 min, 15 min, 30 min, 1 h, 4 h, 24 h, and 48 h, respectively). Only one sample was collected from each mouse. These samples allow monitoring of clinical chemistries (e.g., renal, liver, and hematopoietic function) and rough drug levels. At 48 hours, all mice were euthanized and a terminal blood sample collected by cardiac puncture. After euthanasia, selected animals were necropsied. Tissue samples from liver, lung, brain, and kidney were collected from selected animals after sacrifice. Endpoints initially assessed included daily clinical observations for the 2 day period, body weights, clinical chemistry, complete blood counts, and gross observations of tissues at necropsy. In select cases detailed pathology, with particular focus on liver and kidney function, were carried out. These studies were used to establish IVIC correlations and a MTD.

7. High-Throughput Screen (HTS)

A primary screen followed by receiver operating characteristic (ROC) analysis resulted in the identification of 850 compounds (see FIG. 5A). This was narrowed to 100 compounds having an IC₅₀ of less than 10 μM using a second screen. A graphical representation of the screen is shown in FIG. 5B.

Out of these 100 compounds, three chemical scaffolds were selected for validation. Representative structures of these scaffolds are illustrated in FIG. 6A. Each of these compounds demonstrated the ability to block DCN1-UBC12 binding (FIG. 6B) and inhibit neddylation (6C). Additionally, these analogs were non-toxic to wild type cells and offered synthetic tractability. An overlay these compounds co-crystalized with DCN1 is illustrated in FIG. 6D.

8. Biochemical Validation and Characterization of B7

As shown in FIG. 8 , B7 specifically inhibits DCN1 dependent nedylation.

9. Development of a Structure Activity Relationship

A 1.8 Å co-crystal structure of B7 and DCN1 illustrated five subpockets for optimization (FIG. 9A). A SAR based on B7 is shown in FIG. 9B.

A summary of the potency gains for the 329 series is shown in FIG. 10 .

24. Prospective In Vivo Activity in a Mouse Xenograft Model

The following example of the anticipated in vivo effect of the disclosed compounds is prophetic. An example of an in vivo assay method for assessing the efficacy of the disclosed compounds in an animal model of tumor growth is given below.

Xenograft tumors are first established from an SK-MEL-2 cell culture at the St. Jude Children's Research Hospital Xenograft Core. After these tumors are established as a mouse xenograft model, they are routinely maintained in the CB-17 scid strain (Taconic Farms, Germantown, N.Y.). Experimental animals are prepared by transplanting small pieces of dissected tumors from donor animals into recipient mice. All animal studies are performed in accordance with the St. Jude Children's Research Hospital Animal Care and Use Committee. SK-MEL-2 xenograft tumors were transplanted into male CB-17 scid mice on Day −21. On Days −7 to −5, a jugular vein catheter is surgically implanted into each mouse. Beginning on Day 1, the animals (8 for vehicle, 9 for drug-treatment) received daily infusions of vehicle (10% [(2-hydroxypropyl)-β-cyclodextrin] dissolved in 50 mM Na₂HPO₄/NaH₂PO₄, pH 7.4) or 100 mg/kg of a disclosed compound for 5 consecutive days. Infusions are carried out by placing the animals inside a continuous infusion system (Instech Laboratories, Plymouth Meeting, Pa.), and delivering the vehicle or drug solution via the jugular catheter at a rate of 4 μL/min with a SP230iw syringe pump (WPI, Sarasota, Fla.). Other suitable vehicles are known to one skilled in the art, e.g., 10% Tween 80 or 0.5% methylcellulose in a buffer suitable for infusion dosing. The total volume infused into the animals generally does not exceed 850 μL per day. Tumors are continuously measured during and after infusion periods, 5 times per week (weekdays). Tumor volumes are determined based on the following equation: Tu_(vol)=(δ₁/2+δ₂/2)^(1.5708,) where δ₁ and δ₂ are diameters measured with a caliper at right angles of each other. The size of the tumoar typically range from 0.2 to 0.5 cm³ at the times the infusions were initiated.

For example, compounds disclosed in Tables 1-6 or a pharmaceutically acceptable salt thereof, are expected to show at least partial activity in this mouse model.

For example, compounds having a structure represented by a formula:

A tablet can be prepared as follows:

Component Amount Active ingredient 10 to 500 mg Lactose 100 mg Crystalline  60 mg cellulose Magnesium 5 stearate Starch Amount necessary to (e.g. potato yield total weight starch) indicated below Total (per capsule) 1000 mg 

Alternatively, about 100 mg of a disclosed compound, 50 mg of lactose (monohydrate), 50 mg of maize starch (native), 10 mg of polyvinylpyrrolidone (PVP 25) (e.g. from BASF, Ludwigshafen, Germany) and 2 mg of magnesium stearate are used per tablet. The mixture of active component, lactose and starch is granulated with a 5% solution (m/m) of the PVP in water. After drying, the granules are mixed with magnesium stearate for 5 min. This mixture is molded using a customary tablet press (e.g. tablet format: diameter 8 mm, curvature radius 12 mm). The molding force applied is typically about 15 kN.

Alternatively, a disclosed compound can be administered in a suspension formulated for oral use. For example, about 100-5000 mg of the desired disclosed compound, 1000 mg of ethanol (96%), 400 mg of xanthan gum, and 99 g of water are combined with stirring. A single dose of about 10-500 mg of the desired disclosed compound according can be provided by 10 ml of oral suspension.

In these Examples, active ingredient can be replaced with the same amount of any of the compounds according to the present invention, in particular by the same amount of any of the exemplified compounds. In some circumstances it may be desirable to use a capsule, e.g. a filled gelatin capsule, instead of a tablet form. The choice of tablet or capsule will depend, in part, upon physicochemical characteristics of the particular disclosed compound used.

Examples of alternative useful carriers for making oral preparations are lactose, sucrose, starch, talc, magnesium stearate, crystalline cellulose, methyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose, carboxymethyl cellulose, glycerin, sodium alginate, gum arabic, etc. These alternative carriers can be substituted for those given above as required for desired dissolution, absorption, and manufacturing characteristics.

The amount of a disclosed compound per tablet for use in a pharmaceutical composition for human use is determined from both toxicological and pharmacokinetic data obtained in suitable animal models, e.g. rat and at least one non-rodent species, and adjusted based upon human clinical trial data. For example, it could be appropriate that a disclosed compound is present at a level of about 10 to 1000 mg per tablet dosage unit.

The preparation of such an injectable composition can be accomplished as follows: The disclosed compound and the polyethylenglycol 400 are dissolved in the water with stirring. The solution is sterile filtered (pore size 0.22 μm) and filled into heat sterilized infusion bottles under aseptic conditions. The infusion bottles are sealed with rubber seals.

In a further example, a pharmaceutical composition for intravenous injection can be used, with composition comprising about 10-500 mg of a disclosed compound, standard saline solution, optionally with up to 15% by weight of Cremophor EL, and optionally up to 15% by weight of ethyl alcohol, and optionally up to 2 equivalents of a pharmaceutically suitable acid such as citric acid or hydrochloric acid. Preparation can be accomplished as follows: a desired disclosed compound is dissolved in the saline solution with stirring. Optionally Cremophor EL, ethyl alcohol or acid are added. The solution is sterile filtered (pore size 0.22 μm) and filled into heat sterilized infusion bottles under aseptic conditions. The infusion bottles are sealed with rubber seals.

In this Example, active ingredient can be replaced with the same amount of any of the compounds according to the present invention, in particular by the same amount of any of the exemplified compounds.

The amount of a disclosed compound per ampule for use in a pharmaceutical composition for human use is determined from both toxicological and pharmacokinetic data obtained in suitable animal models, e.g. rat and at least one non-rodent species, and adjusted based upon human clinical trial data. For example, it could be appropriate that a disclosed compound is present at a level of about 10 to 1000 mg per tablet dosage unit.
